Breaking force
MP samples prepared at a concentration of 4 g/100 g could be
successfully induced to gelation, even at 1.8 g/100 g NaCl, while
those without MTG could not produce viscoelastic gels (data not
shown). This suggested that the cross-linking of fish MP could be
catalyzed by MTG although the salt content was lowered.
When different NaCl levels were considered, the strength of the
MP and SP mixture gel prepared at 1.8 g/100 g NaCl was a higher
value than that at 2.6 g/100 g NaCl. Based on the gel strength data, a
reduction of NaCl concentration would not only reduce NaCl content
in protein gel, but also improve textural properties (Table 2).
Ramirez, Angel, Uresti, Valazquez, and Vazquez (2007) reported
that reducing salt content from 20 to 10 g/kg did not affect the
textural properties of restructured products prepared from striped
